A/N: I never thought it would take me this long to write a DP fic. Then again, I also never thought I'd write a MerDanny fic, but well, here we are. This will (hopefully) be first Multi-chapter fic, but I am notorious for starting things and then forgetting them, so don't be afraid to remind me (Politely) to update. Enjoy.

Disclaimer: I own nothing but a laptop, some pocket lint and my own imagination.

3/11/2017: I realized that the lack of line breaks in this chapter made it really hard to read, and a lot of new people were probably getting turned off the story because of that, so I added them in to make it consistent with the chapters that follow. The rest of the text has not been altered. I considered editing it, because honestly, I feel this isn't reflective of my best work, but I kinda felt like that'd be... I dunno. Dishonest I guess? At any rate, I felt like it'd be better to leave it as is.

It started with a storm.

The research vessal rocked and swayed, and muffled crashes from below told Danny that his parents would be needing a new set of beakers soon. He knew that he should get to his room and wait it out, as he always did, but something stopped him.

A voice. A strange, beautiful voice. It sang, loud and clear and pure, from what seemed to be everywhere at once. The waves filled with it, and the words were felt rather than heard.

'Remember, Remember, you will remember my name.'

Why was he running again? He didn't want to leave. He suddenly wondered why on earth he was up here, on deck. The Voice was in the ocean. He wanted... no he needed to be where the voice was. So naturally, he should be in the ocean too, right? Something in his head protested that that was not a good idea, but he quited it. Of course, this was a good idea. Really why hadn't he thought of it sooner? He should have just jumped in a long time ago.

He heard his parents running up the stairs, and, dimly he regestured them calling out to him, saying something about Sirens. Ughh, more of their mermaid talk, agian. When would they understand that such things weren't real? Nothing was real but the voice. Ignoring their shouts, he jumped in to the waves, heart swelling with the prospect of joining the voice.

The moment the icy water hit him, the voice went silent, and the joy bleed from his heart as quickly as it had come, terror filling the void. He struggled and kicked upward, lungs already starting to burn, eyes stinging with the salty water. But his efforts were pointless, he was in a current, and a strong one it seemed. He heard screams above, accompanied by two splashes, which he knew were his parents, though whether they had been knocked overboard or dived in after him, he did not know.

He would have to breath soon but he could not reach the surface. He was going to die here. He was going drown here becuase of some stupid voice...

There was somthing nearby. He knew it. He could feel it. It wasn't anything solid, it was... the best way to descibe it was a sort of energy. It pulsed brightly, with a greenish-silver light. Somehow Danny knew that it was alive, in fact he vaguely remembered seeing something similar in jars in his parents lab, though he could not be sure. He felt that perhaps he should try and avoid it, but it did not matter. The current was to strong, to fast to fight. His lungs were burning furiously now. He would die soon anyway.

The light was close enough to touch by the time he finally gave in, relingushing the breathe from his lungs, gasping and choking as water filled the void. Unconciousness threatened to consume him, and his last thought was that the light was doing somthing. It was going inside him, phasing into his chest, but conciousness had already left him before he could process this.

(Line Break)

It had never had a host like this before. This creature (human, it believed was the proper term) clearly did not belong here. In fact, it seemed quite unfit for life in the sea.

Well, now. That would have to change, wouldn't it? It slipped into his cells, rearranging them, making adjustments where needed. Let's see... yes. These limbs here, these legs, they'd need to go for now. Simply not practical you see. No, a tail is what the creature... the boy... needs.

Yes... just leagthen these out a bit, merge it together here and... yes, perfect.

The arms, it supposed, could stay (they would likly come in handy later), but these digits here would need some webbing.

Hmm... now for the tricky part. The lungs. What to do with the lungs. It supposed that it should keep them, the boy would likly want to go back to the surface soon. But he would not last long if he had to come up every two minutes. Hmm... wait.

It moved upward, towards the area in question. If it expanded these abit... yes! Wonderful! Now he (they, perhaps? It felt that it was a part of the boy now) could stay underwater for a good while before he needed breathe.

It felt the boy starting to come to, awareness seeping in. It made a few more adjustments before relingushing control, content to let the child take it from here.

(Line break)

Danny's eyes opened, and he surrveyed surroundings. He was still in the current, but the light was nowhere to be seen and he felt... different. Why was he alive? And... wait. Why could he see so clearly?

He tryed to swim towards the surface, and in doing so realized two things. First, that he was now strong enough to break free from the current, and secondly, that he didn't have legs anymore.

Looking down, he saw that the place where his legs ought to be was now occupied by a sleek black tail, but not the kind he normally imagined a merman would have (for he supposed that's what he must be now, though for some reason, this failed to startle him as much as it should have). This was smooth and scaless, and if he had to guess, he'd say it was that of an orca, although, seeing as he was off the coast off California, that didn't make much since. Experimentally, he gave it a flick, and found that he could propel himself easily towards the suface. Breaking the surface, he found he could still breathe normally. Still a mammal then. Good.

Spotting a rock nearby, he swam toward it, suprisingly fast. With some difficulty, he finally managed to heave himself onto it, noting that his new tail was much heavier than he anticipated.

The sun, which had been setting when he so stupidly decided to jump in (He still didn't know why he did that, but he supposed it could have been a Siren, as it seemed to fit.), Had just vanished below the horizen, meaning that he'd only been out for maybe 45 minutes or so, which he supposed wasn't that bad. The storm had vanished without a trace, and the waves were gentler now. Glancing at his reflection in the water, he saw that his messy black hair was now silvery white, and strangly dry. Upon closer inspection, he noticed that his eyes were green now, and apeared to glow in the moonlight (reflective probably. He'd seen this in seals before). His fingers had thin black webbing between them, and, upon opening his mouth, he found that his teeth were sharper now. It made sense. According to his parents, merfolk were mostly carnivores, so it followed that they'd need sharp teeth.

Wait...his parents! They'd fallen overboard hadn't they! He needed to find them, now!

Hoosting himself up as high as he could, he searched the waves for some sign of them, a glimpse of his moms red hair, or his dads orange hazmat suit. Finally he spotted them, about a hundred yards away, drifting near the shore.

It didn't take him long to reach them. They were unconcious, which he supposed was a good thing, because he'd really rather they not see him like this. Grabbing them both by the arms, he dragged them forward, determined to get them to dry land. As he swam, he made another realization. He was alot stronger now, as he was able to carry his father (who even with the bouyancy of the water, was extremly heavy) with minimal effort, a feat that he was sure very few could ever accomplish.

They were very close to shore now, and Danny soon found that the water was to shallow to swim an farther.

I wish I had legs again. I need to get them ashore, and I don't want to be this way forever.

He felt something stir in the back of his mind, and a thought drifted to the for-front, one that was most certainly not his own.

But of course.

A strange warmth rose in his chest, he felt the light from before moving through him, changing him. Tail became legs. Fins shrank and vanished. Sharp teeth dulled into somthing more human. The exprience was oddly painless, and the only evidence left afterward that he was anything more than human was the still present (Though now skin colored) webbing connecting his fingers and toes.

He stood and walked to shore, laying his parents in the sand. As he checked their pulses and made sure they were truly alright, he wondered what he would tell them when they awoke. They might think he was crazy, and even if they did believe him... their view of merpeople wasn't exactly positive. No. He couldn't tell them, not yet. Maybe some day, but not now.

Finishing his work, he sighed. His life was weird, always had been, always would be, but this...

He didn't know what he was going to do, but he knew one thing. His life, his very exsistance, had just changed forever.

A/N: Well, there ya go. Let me know what you thought (REVIEWS GIVE ME LIFE) and let me know if there's anything you didn't get, or if there's a mistake somewhere that I didn't see.

Flamers shall be locked in a room with the box ghost and forced to listen to him monologue for the rest of their days.
